If the pump is set at 60% speed and 70% stroke length, the
approximate pump output is:
24.0 x 0.60 x 0.70 = 10.08 GPD (gallons per day) Divide by 24
(hours in one day) to calculate GPH (gallons per hour).
If pump is not equipped with speed adjustment, calculate by
Max Pump Output x % Stroke only.

CALIBRATION
Once installation is complete and the approximate output has
been determined, the pump may be calibrated to adjust speed (if
equipped) and stroke for your actual desired output.
1. Be sure the pump is primed, and discharge tubing and
Injection Check Valve are installed as they would be in
normal service (i.e., including factors such as injection
pressure, fluid viscosity, and suction lift).
3. Place the foot valve in a graduated container with a
volume of 1000 ml or more.
4. Start the pump and run until all the air is exhausted from
the suction line and head.
5. Disconnect power to the pump. Refill graduated
container to a level starting point.
